Ceramica Zirconia Toughened Alumina (ZTA) prezint\u0103 o \u00eembun\u0103t\u0103\u021bire considerabil\u0103 a rezisten\u021bei \u0219i tenacit\u0103\u021bii fa\u021b\u0103 de ceramica din alumin\u0103.Con\u021binutul tipic este de la 10% la 20% zirconiu. Atunci c\u00e2nd o fisur\u0103 se dezvolt\u0103 prin ceramic\u0103, structura cristalin\u0103 a particulelor de zirconiu din regiunea fisurii se schimb\u0103 de la faza tetragonal\u0103 metastabil\u0103 la faza monoclinic\u0103 stabil\u0103. schimbarea cre\u0219te volumul particulelor cu aproximativ 3-4% \u0219i produce tensiuni de compresiune \u00een matricea de alumin\u0103.
